Now
that we've set the grid up, let's set up how the lines will look. Twirl
down the arrow next to Line Attributes. Move the Time Marker to 04:00,
so we can see what the lines look like as we change the parameters. At
this point the lines will look like this:
As
you might guess this looks nothing like our final movie, so let's start
getting there.
First
off we want our lines to be much longer, so change the Minimum Length
to 100 and the Maximum Length to 200. We want the lines to stay on the
screen for 4 seconds, so change the Lifespan to 120. Lifespan is set in
frames, so 120 frames is equal to about 4 seconds at 29.97 frames a second,
which is what our comp is set to.
At
this point our lines should be arranged like a street map... or a waffle.
See what you want to see. It's all about your artistic interpretation.
:-)
Let's
vary the thickness a little bit, so change Thickness Randomness to 50.
Now
we'll start getting into the stuff that's going to make our lines start
looking like the final movie.
Change
the Corner Size to 100. The Corner Size determines the radius of the turn,
when a line makes a turn. By cranking this up, we end up with sweeping
curved lines. Play around with this a little bit, just to get an idea
of what looks different sizes will give you.
Now
twirl down the Color section. Change the Start color to a dark blue and
the End Color to a lighter blue.
That
should give us this:
.
So
render this out and take a look at it or just click on the above image..
Make sure you switch to Best Quality. It's a neat effect, but with a little
tweaking we can get a few different looks.
If
you want to change things up a bit, try changing the Corner Size Randomness
to 50. That will give you this:
Now
let's set up the Grid Adherence section. This determines how closely the
lines stick to the grid. Back at the beginning of all this I mentioned
that the lines follow the rows and columns. Grid Adherence is what makes
them do that. By default, it's set up to make the lines stick to the rows
and columns like glue. However, you can change that, so the lines only
more or less stick to the grid. Set the Grid Probability to 50%. This
means that about half the lines will stick to the grid and the other half
will be off by some amount. That amount is set by the Grid Adherence Amount.
Set that to 20. Set the Grid Adherence Randomness to 50%. This varies
the Grid Adherence Amount from line to line. Some lines will be 10 pixels
off the grid, some will be 20, some will be 2.
After
you do all that it'll look like this:
Now
we'll do one last thing.
Go
back to the Producer Point section and change the height to 200 and Width
to 300. That will spread the origination point of the lines out and have
lines starting from all over the place. It'll look like this:
So
there you have it. Lines flowing all over the place willy nilly and it
only took you a few minutes. Try creating something similar by hand, it'll
take a lot longer.
The
only hard part is getting your head wrapped around the grid that's controlling
the lines. Play around with Grid Adherence to really understand what's
going on there. Once you've got that down all the Geomancy filters are
pretty easy to control.
